About this file
This is a technical standards document for single-channel microwave systems designed for federal government use, specifically for extending radio control infrastructure across multiple sites in tactical, wildfire, and long-range federal deployment scenarios.
The document establishes mandatory requirements for all new microwave systems, which must be digital, support ethernet high-bandwidth transmission, and utilize standard network equipment without conversion to analog or other formats. Systems must operate in the Federal Government's 4.40–4.99 GHz band (NATO Band IV) with licensed spectrum use and comply with local regulatory authority rules. Key technical specifications include channel sizes of 5–45 MHz with Dynamic Spectrum Optimization for automatic interference avoidance; data rates up to 450 Mbps with adaptive modulation from BPSK to 256 QAM and FEC coding; maximum transmit power of 27–29 dBm (18–25 W) with receiver sensitivity up to –97 dBm; integrated panel antenna with 21 dBi gain or external dish rated IP66/IP67; power supply options of 48 VDC or 90–240 VAC; operating temperature range of –40°C to +60°C; and MIL-STD-810G ruggedization. Security requirements mandate 128/256-bit AES encryption, HTTPS, SNMPv3, and FIPS 140-2 NIST validation with native Suite B/SNSA algorithm support and end-to-end encryption. Systems must support SyncE, IEEE 1588v2, and HCMP (High Capacity Multipoint) for incident-based topologies with real-time interference avoidance and channel changes without link disruption. The document cautions that commercial 4 GHz band systems not operating in USFS federal spectrum and lacking FIPS validation do not meet these federal standards.

Technical Standards for Single-Channel Microwave Systems
For single-channel microwave systems, the technical standards define the operational, regulatory, and performance requirements that ensure compliance and interoperability.
Microwave Backbone Systems
Microwave radios are used to extend radio control infrastructure beyond that provided by other means such as UHF Radio Control. Other methods such as T1 circuits, or legacy copper cable have become either obsolete or excessively costly to lease and operate.
Where microwave control circuits are required to transport used for control between sites, the following criteria will apply:
1. All new microwave systems will be digital and support ethernet high bandwidth transmission.
2. Microwave circuits will be configured as ethernet and utilize standard network equipment.
3. New digital microwave equipment will interconnect without conversion to analog or other formats.
1. Frequency Bands and Licensing
Fully supports Federal Government’s 4.40–4.99 GHz band (NATO Band IV), which is the NTIA-allocated federal spectrum used by U.S. federal agencies.
Requires licensed spectrum use and must adhere to local regulatory authority rules.
Designed explicitly for federal, defense, and public safety missions in tactical, wildfire, or long-range federal deployments.
2. Channel and Bandwidth
Channel sizes 5–45 MHz; supports Dynamic Spectrum Optimization (DSO) for automatic interference avoidance everything RF+1.
3. Data Rates and Modulation
Up to 450 Mbps throughput; supports BPSK to 256 QAM with adaptive modulation and FEC coding everything RF+1.
4. Power and Sensitivity
Max transmit power 27–29 dBm (~18–25 W) everything RF+1; receiver sensitivity up to -97 dBm (5 MHz channel) everything RF.
5. Antenna and Gain
Integrated panel antenna (21 dBi gain) or external dish; IP66/IP67 rated everything RF.
Fanless and sealed all outdoor design.
Rapid alignment with optional beam-steering smart antenna.
6. Environmental and Power
48 VDC or 90–240 VAC; 35 W; -40°C to +60°C; MIL-STD-810G ruggedized everything RF+1.
Proven survivability in wildfire smoke, ash and high altitude cold starts. Designed for tactical and tactical fire deployments.
7. Security and Compliance
128/256-bit AES encryption, HTTPS, SNMPv3; FIPS 140-2 NIST validated everything RF+1.
Native support for Suite B/SNSA algorithms. End to end encryption built into radio.
8. Standards and Protocols
SyncE, IEEE 1588v2, FIPS 140-2, MIL-STD-810G AT Communication International.
9. Other
Real-time interference avoidance.
Channel changes without dropping the link.
Supports HCMP (High Capacity Multipoint) for incident-based topologies.
Summary
Some Microwave Systems that operate in the 4 GHz band are commercial systems vice federal. These systems do not operate in USFS federal spectrum and are not FIPS validated. Single-channel microwave systems are designed for high-capacity, secure, and compliant backhaul links. They must operate within licensed frequency bands, meet power and sensitivity limits, support adaptive modulation for interference avoidance, and comply with national/regional spectrum and security standards. For deployment, operators should verify local regulatory requirements and ensure antenna and environmental specs match site conditions.
